To all whom t may concern: 1 A

Be it known that I, ADoLrH JAECKEL, a citizen of the United States,residing at Milwaukee, county of Milwaukee, and State of Wisconsin, haveinvented new and useful Improvements in Friction-Clutches, of which the'followingis a specification. i Y My invention relates to improvementsin friction clutches of that type in which a set of friction clutch"disks connected `respectively with the driving and driven member, n arepressed togetherV for the transmission of motion. The object of myinvention is to provide means, operable from an ordinary shifterlsleeve, for setting the clutch lwith balanced and adequate pressure uponthe disks, and locking the shifter' in clutch settingposition. Also toprovide a keyless clutch of the described type in whichy the clutchsetting pressure will tend to bindv the clutch more securely upon asupporting shaft. K In the drawings-Figure 'I is longi-` tudinalysectional view ofl my improved clutch drawn' on line` vof f FigfQ; Fig.2' is aj side elevation par'tin section on a plane exposing one of theclamping bolts.

A sleeve i tubular socket, whichreceivesja split tubular wedge member Chaving .a flange C on vits projecting end the flange'C is pro-Y videdwith' threaded' apertures Cf to receiveL a suitable tool for withdrawingthe wedge member when itis desired to separate the parts. Then the wedgemember `(l is forced into the socket, it is compressed upon shaft B,-which extends through yit and y through the' sleeve A, andthereforeserves to frictionallyplconnect the sleeve and shaft to revolve inunison. A loose sleeve E, on the shaft, isprovide'd with a ,projection EY supporting a rim F. This rim F carries an f l' which constitutes` oneinturned flangey or open centered" disk Gr v member of the set offriction disks.

ried by the sleeve the disk I-I. being fixed thereon, and the disk Ilongitudinally movf able along the sleeve. The diskGr is pref-1 erablyprovided,';on its side faces, with rings J which bear directly upon thedisks f II and I when the several disks are' in clamping relation. f

A set of elbow cranks are pivotally con` nectedwith `the disk I, withshort arms K extending inwardlyn and long arms L projecting along the.yshaft therefrom, and conknected by links M with a shifting collarfN. Y

A yoke O loosely encircles the sleeve A. The elbowcrank arms K engagetheinner face of this yokeon opposite sidesof the shaft, and a set ofbars P, carried bythe v collar N, are adaptedto bear against the outersurface ofthe yoke opposite thebearing points of the elbowlevers to`limit the inward movement ofthe shifting collar. Between the elbowcranks, the yoke bends inwardly` on each side and is connected by..

va clamping bolt Q with the flange C, said clampingbolts lextend throughthe flanges C, in screw threaded engagement with each f of saidyflanges. A nut R on bolt Q, provides means for adjusting the span'between the yoke and flange C. A spring S is coiled upon each bolt Qbetween the disks H and I and tends to separate `the disks andrelievethem from binding fric.m y y t ,v tional contact uponintermediate disk Gr.` A on shaft B is provided with a ."In operation,the clutch is set `by moving collar N inwardly.
